A somewhat overlooked environmental problem is the environmental impact from Pig/Cow/Chicken Farms. They are awful for the environment by dumping feces into the water, which eventually leads to hypoxic environments, and dead zones. Sad stuff.

The over 100 estuary dead zones increasing in size and quantity are mostly from agricultural runoff, specifically mostly fertilizers. Various hogs, cattle, goats, sheep, chickens, turkeys, and other domestic animal farms and ranches have a variable amount of mismanagement of wastes. There are many industrial and urban toxins also increasing, and worldwide oceanic mercury from coal fired steel and power plants. The thing acidifying the oceans the most is human caused atmospheric CO2. Although deforestation and ocean acidification are lowering oxygen a small amount so far, the main thing affecting the ozone layer is still chlorine and fluorine based compounds from humans.The mechanism of thermageddon is CO2 to high enough Arctic temperatures to cause a positive feedback loop with tundra methane deposits and open ocean warming to oceanic methane hydrate deposits self releasing until global "turnover" and a thermal max episode 30 times faster than PETM with effects at least three times worse and 50% longer.Almost completely separate from that is the human overpopulation to lack of aquifer and surface pure water, lack of enough food from a variety of soil, water, and climate factors, to a crash in numbers in a cascading manner around the world, to a survival rate of 5 to 10%, around the 2030s to 40s starting and ending 2060s to 80s. Temperatures will continue to climb if the tipping points have been crossed, until thermageddon totally arrives 2300 to 2500AD. ~90% extinction rate, with oceanic life and equatorial life doing the best. Probability of Ecocide for humans is very high.This life, like the thermal vent life in the oceans will provide stock to mutate into a myriad other life forms over the next 3 million years.Unless, somehow, people keep burning all the rest of the fossil fuels they can get, and they start a runaway "Venus Effect".

I do believe that they cause a serious problem for acidification which is on the charts of the bigger than ozone depletion.

Acidification causes lack of oxygen in the water, essentially all sea life is dead, which in turn kills the microorganisms, which in turn makes the 50% of Co2 which is transformed by microorganisms to oxygen released into the ozone, which creates massive global warming, which kills mankind.

You seem to not have read the top paragraph, tommeee......eee.......eee........eee

Just because you post it doesn't mean it reflects what's going on globally. Human sewer waste is a big issue, more so in place like Asia, Africa and S/America. Urine is a perfect food in a soluble form ready to go.

Human excrement in rivers and running out into the ocean from coastal cities, from semi-deep drains like in Vancouver, is all part of the nutrients for the algae and bacteria blooms, along with red tides, that make the dead zones near estuaries.. The human excrement part is larger in Africa, and Asia, especially India and with it waterborne diseases, and 200,000 people in each large city who never use a real toilet in their lives. Only in few rivers is it a greater load than farm fertilizer runoff with uncomposted animal wastes. Recently in China, a river had 26,000 pig carcasses in it. The farmers could not afford to feed them any longer or dispose of them properly, and became pigs themselves, in a way. In the 1980s the North Sea had a massive fish die-off from the diminishing returns of increased chemical fertilizers in river runoff from fields, killing the entire fishery for 5 years and only getting back to 50% since then. The estuary dead zone problem didn't start to get bad until the 1970s when the Earth had half the overpopulation of today. You can be talked into thinking urine is good to drink, and do it. We are all drinking dinosaur urine that has been naturally purified.

The other problems outside the estuaries such as the high plastic trash content in the Med and Black Seas, and the 6 huge oceanic trash gyres, the extreme over harvesting and throwing away of "garbage" species, the acidification from HGHGs hurting corals and shellfish and their eco-systems, high mercury content in top of the food chain fish, other chemicals and toxins, and generally noisier environment for sea mammals and fish, all to the point of odd beachings and local die-offs. Plus the warming of the oceans 0 to now 1400 meters deep, disrupting sea life and getting closer to rapid methane releases.Other problems are hitting rivers and lakes with mercury fallout from dirty coal power of China and India and some from here when the rules were relaxed to appease big coal. It limits even the trout you can eat from pristine mountain lakes. Rivers have not been able to be cleaned up enough by upstream users, from various industrial and agricultural chemicals to birth control pill hormones which do some remarkable sex changes in downstream fish and perhaps, over time, other creatures. They get into farmed fish and are not checked enough for mercury and other toxics. Excessive salts in some irrigation rivers is destroying farmland by salination, while aquifer irrigation is getting close to empty and the loss of 5/6 of yields in affected areas. Already, conflict with water is common, and the cities win over the farmers in California and here this year in Colorado. I do hope this is understandable to readers.

Not to forget the decades of dirty coal power from US plants having similar impacts, because the US only recently began a control plan for mercury emissions and exempted power plants from hazardous emission regulations.

Free range field meat instead of stock yards and crowded pens would be a good place to make a start. Then the manure is more spread around and can be instantly recycled into plant growth instead of run off as a toxic soup. Of course there are necessary refinements to that but in principle if you aren't into being a vegan, field to slaughterhouse is the way to go. It's pretty much fossil fuel neutral. The kind of animal would be adapted to the natural landscape, not requiring tree removal as you see in the Amazon. In fact trees that have been removed should be restored as much as possible. As for animals, bringing back the buffalo and wild turkeys might be an example. Speaking of other underused native foods how about acorns, an Indian staple. It's not so great by itself but after leaching out the tannin it blends well with various foods.
